Binding tabs

Abstract

A tab for adhesively securing and binding articles within looseleaf binders and like devices, where such articles cannot be conveniently provided with apparatus for engagement by the binder rings. The tab includes a central, apertured portion advantageously comprising bilaterally symmetric apertured sections separated by a central fold line, and wing portions, all adhesive-coated. The tab is prepared for use by folding the respective halves of the central tab portion against each other with apertures aligned. The tab may then be inserted in a binder ring, and the wings of the tab adhesively secured to the article to be bound. Advantageously a plurallity of such tabs are included in a tab stock, such tab stock including an adhesive coated tab substrate (preferably transparent) and backing sheet.

We claim: 
     
       1. A tab for binding articles in looseleaf binders, comprising an elongate foldable flat strip which is bilaterally symmetric around a central fold line, said tab having two apertured portions having respective discrete apertures on opposite sides of the central fold line, and first and second wing portions at the opposite ends of said elongate tab, wherein one face of the strip is coated with pressure sensitive adhesive and can be folded along the fold line and its apertured portions adhesively secured to each other with their apertures aligned, whereupon the wing portions can be adhesively secured to the article; said adhesive coated strip being releasably adhered to a carrier sheet which is divided into separately removable portions respectively adhered to the apertured portions and wing portions of the tab. 
     
     
       2. A tab as defined in claim 1, wherein the first and second wing members and the adhesive are transparent. 
     
     
       3. A tab as defined in claim 1, wherein the strip is rectangular. 
     
     
       4. A tab stock laminate comprising a tab layer, a pressure sensitive adhesive layer backing the tab layer, and a release sheet removably adhered to the adhesive layer; said laminate being separable into a plurality of tabs, each tab comprising a bilaterally symmetric elongate strip with a central fold line, first and second apertured portions having respective discrete apertures on opposite sides of the central fold line, and first and second wing portions at opposite ends of the strip; said release sheet being divided into separately removable portions respectively backing the apertured portions and wing portions of the tabs. 
     
     
       5. A tab stock laminate as defined in claim 4 wherein the individual tabs are separable along perforation lines. 
     
     
       6. A tab stock laminate as defined in claim 4 wherein the individual tabs are separable along score lines. 
     
     
       7. A tab stock laminate as defined in claim 4, wherein the tab layer and adhesive layer are transparent. 
     
     
       8. A tab stock laminate as defined in claim 7 wherein the tab layer is comprised of transparent foldable plastic and the adhesive layer comprises pressure sensitive adhesive. 
     
     
       9. A tab as defined in claim 4, wherein the median fold line is printed on the tab layer.
